Definitions

  • the present invention relates to a self-piecing nut driven into a metal plate and fixed thereon in a caulking fashion with a nut body self-comprising a pilot portion functioning as a punch for punching out a metal plate, and in particular, it relates to a self-piercing nut usable for a high tensile steel plate or common steel thick plate.
  • Self-piercing nuts have been conventionally employed in large quantities in the automobile industry and for assembling household electrical appliances. When a self-piercing nut is fixed on a metal plate, it is required to have a predetermined rotational drag and pull-out drag. In order to meet the requirement, various types of self-piercing nuts have been made available one after another.
  • a conventional self-piercing nut is generally used for a common steel plate, and an outer periphery surface of the pilot portion that punches out a metal plate for assuring a rotational drag is formed to have multiple surfaces such as square and hexagonal surfaces, and many concave-convex (knurled) portions are disposed on the outer periphery surface.
  • a protrusion is disposed at a hole periphery of the punching die which punches out a metal plate in cooperation with the pilot portion, and the protrusion is press-fitted into the opening periphery of the punched-out metal plate, then the opening periphery is deformed and tight contacted on the outer periphery surface of the pilot portion, thereby obtaining a rotational drag and pull-out drag.
  • a self-piercing nut such that a polygonal concave groove is disposed on a fastening seat surface extending from the base of the pilot portion to the outer periphery of the nut body, and further, a convex portion is disposed at a bottom of the concave groove, and the opening periphery of the metal plate punched out by the pilot portion is press-fitted and deformed in the concave groove by means of the protrusion of the die, thereby obtaining a rotational drag and pull-out drag.
  • the above-mentioned self-piercing nut is usually manufactured by quenching and hardening the whole thereof after pressure molding by using common steel. Therefore, from the hardness viewpoint of the piercing nut itself, it is often used for a metal plate whose thickness is about 1.4 mm or less in the case of common steel plate material.
  • a self-piercing nut for thick plate also usable for thick plate (common steel) of 1.4 mm or over in thickness is proposed by the inventor et al as in Patent document 1 (JPH2-52125) and it has been already materialized.
  • FIG. 16 shows self-piercing nut 31 mentioned in Patent document 1
  • FIG. 17 is an explanatory diagram of the process of fixing the self-piercing nut 31 on metal plate 32 .
  • Self-piercing nut 31 is substantially circular in shape with respect to the periphery of end face 35 of pilot portion 34 that functions as a punch for punching out metal plate 32 , and thereby, it is possible to use punching die 40 for making a hole having a circular section.
  • opening periphery 33 of metal plate 32 punched out by the cooperative operation of pilot portion 34 and punching die 40 is press-fitted into annular groove 37 disposed at the outer base periphery of pilot portion 34 by means of protrusion 41 disposed at the hole periphery of punching die 40 , and it is also fitted into concave groove 36 disposed at the outer periphery surface of pilot portion 34 in order to secure self-piercing nut 31 on metal plate 32 , thereby obtaining a rotational drag and pull-out drag.
  • the object of the present invention is to provide a self-piercing nut usable for a high tensile steel plate and common steel thick plate (3.0 mm to 12.0 mm in thickness), solving the problems as mentioned above.
  • the present invention employs technical means as described in the following.
